Function

This Step is used to perform intelligent recognition of characters such as letters and numbers in images. Through image acquisition, and ROI selection, the system uses deep learning for training and validation to output character recognition results.

Using this Step requires the "Lite AI" feature license. Please contact Mech-Mind sales to obtain it.

Usage Scenario

This Step is suitable for character recognition scenarios with complex backgrounds, multiple fonts, or irregular characters. This Step typically follows the 2D Smart Camera Step, or Steps such as 2D Matching. The former is suitable for scenarios where the target position is relatively fixed, performing recognition judgment after acquiring image data; the latter is suitable for scenarios where the target position may shift, using alignment Steps to obtain the target’s pose transformation parameters, which are input to this Step to synchronously adjust the ROI position for stable recognition judgment.
